A Block of Mass M = 5 $v _ { \mathrm { i } } = 6.5 \mathrm {~m} / \mathrm { s }$

A block of mass m = 5.6 kg, moving on a frictionless surface with a velocity of $v _ { \mathrm { i } } = 6.5 \mathrm {~m} / \mathrm { s }$ to the right, collides with a block of mass M at rest, as shown in the figure. After the collision, the 5.6-kg block recoils with a velocity of $v_ \mathrm { f } = 0.70 \mathrm {~m} / \mathrm { s }$ to the left. If the blocks are in contact for 0.20 s, what is the magnitude of the average force on the 5.6-kg block, while the two blocks are in contact?

A) 202 N
B) 192 N.
C) 182 N
D) 0 N
E) 0 N.
